300 BLK has no cycling issues if you for example buy an AAC brand upper or rifle, or one that works as well.

All 300 BLK uppers use a normal Colt M4 spring.

I would't describe it that way. It is all about gas port size. The correct gas port size for a pistol length gas system does not allow H110 or Lil'Gun to cycle with subsonic.

No - 300 BLK is much closer to 308 than you think. Let me give you three examples:

110 grain TAP 308 is 2800 fps from a 16 inch barrel. It drops to the muzzle velocity of 300 BLK at 130 yards. So...

308 is much more effective, but it is a lot more recoil and the guns are much heavier. I have struggled with the 308 vs 5.56mm debate in the past for my own home defense, and I really wanted to make...

Actually in every case I have seen, if a gun won't run subsonic, it is simply because the manufacturer made the gas port too small or speced too heavy a buffer.

300 Whisper is a proprietary version of the 300-221 Wildcat. 300-221 came before 300 Whisper(R), not after. Also, cartridge names (at least in SAAMI) never begin with a . So it is 300 BLK, not .300...

Quoted for posterity. What does 6.8 have to do with it? 6.8 has more expensive ammo, requires a custom bolt, custom magazines, does not hold 30 rounds, the military never adopted it, etc.

1/2-28 threads are possible on a 30 cal, but no one does it. 9mm cans will get hot very fast with subsonic ammo, and cannot be used with supersonic ammo.

AAC makes a 12.5 inch upper.
